CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 259,534, dated June 13, 1882.

Application filed May 3, 1882. (No model To all whom it may concert:

Be it known that I, GEORGE M. HARBAUGI-I,

a citizen of the United States, resident at Sabillasville,in the county of Frederick and State 5 of Maryland, have invented a new and valuable Improvement in Gar-Couplings; and I do hereby declare that thefollowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical sectional view of my car-couplin g. Fig. 2 is a cross-sectional View of the same. Fig. 3 is a horizontal section through the cover, showing a top, view of the coupling. Figs. 4, 5, 6, and 7 are detail views, and Fig.8 is a perspective view of the coupler.

This invention has relation to devices for coupling cars; and it consists in the construction and novel arrangement of the abutmentguide projecting above the top of the drawhead and the reciprocating trip, the pin-jack and itsjointed arm or prop-catch, and the solid flat link-bar having end slots.

The invention also consists in the removable abutment having arms extending downward into recesses in the head and the horizontal locking-pins engaging said arms, all as hereinafter set forth.

In the accompanying drawings, the letter A designates the front portion or body' of the draw-head, having the link-opening B made centrally through it. This link opening or passage Bis formed with flaring mouths O in front and rear, which are connected by a comparatively short neck portion or throat, a, whereof the sectional opening is only sufficient to allow the flat link-bar D to work therein with ease. Through the sides of the head A are made horizontal passages or holes I), to receive the arms or bolts 0, by means of which the open rear bar, E, of the draw-head is secured to the head A.

ings 6 near each end. The link-bar is somewhat tapering or pointed at each end, as indicated in the drawings, in order to facilitate its entry into the flaring mouth of the draw-bead, whether presented true or somewhat indirectly.

Gr indicates the abutment, which projects upward from the top of the draw-head, and is provided on its rear transverse face with guides g, in which the sides of the pin-slide H play. A passage, h, is made vertically through the abutment and head to the throat a, said passage being enlarged at its upper end, It, and at its lower end, I. In this passage is seated the vertical reciprocating trip K, thelower end, an, of which is somewhat larger in diameter than its neck portion to correspond with the enlarged lower end, I, ot'the passage h, in which it plays.- This end at of the trip is rounded underneath, and when in its lowest position projects into the neck a from above. in the upper enlargement, it, of this passage is seated the head if of the trip, which is laterally beveled on top, so that when the trip is in its lowest position the lower edge of the top will be below the stop-wall s of the passage.

L indicates the lever or pin-jack, one end of which is pivoted to a post, P, projecting from the top of the head. This lever extends laterally toward the side of the car, and is designed to enable the pin to be easily raised without going between the cars. The lever is provided with an arm, R, which is jointed at n, and the pivoted end or prop-catch z is angular in form and projects forward over the abutment. To the lever is pivoted, at 'r, the pinslide H, which is of flat form, having a rounded pin portion, 19, projecting downward and designed to engage the pin-hole a of the head when in its lowest position. When the lever L is down, the link being in position and engaged by the pin, the jointed arm R is level, or nearly so, and its upper surface is about even with that of the highest portion of the abutment. 'Its catch end is then seated on a lower bearin g portion, to, of the top of the abutment, as indicatedin the drawings. When the lever is raised the arm R rises, as the pin is drawn upward, to free the link, and the pivoted prop-catch 2 falls into engagement with the stop-wall s of the abutment as the link is withdrawn from the draw-head. At the same time the trip K falls into its lowest position.

The lever and its pin are now set or held up by the prop-catch, and the draw-head is therefore ready to receive the link. As the link enters it raises the trip K, and thereby disengages the prop-catch from the stop 8, allowing the lever to fall, and the pin, which is pivoted thereto, descends, engaging the aperture in the link. The coupling operation is therefore antomatic. In order to prevent premature action on the part of the trip, the faces of the linkbar at each end are centrally grooved or recessed at a, so that the end of the bar can pass well into the link-passage and under the pin before the trip is raised.

The abutment G is usually made separate from the body of the head, and is formed with arms I), which extend downward into seats or apertures 0, made in the head on each side of the central opening. In the head are also formed smaller passages or perforations d, extending transversely and horizontally from each side wall of the head, so as to intersect the seats or apertures c, and in these perfora-. tions are inserted pins 0, which pass through openings 9' in the arms of the abutment. The outer ends of the pins are designed to be secured by hooks, slide-pins, or other common fastenings.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a car-coupling, a link-operated vertically-reciprocating trip, K, in combination with a pin-raising lever having a jointed arm, It, terminating in a prop catch, 2, substantially as specified.

2. In an automatic car-coupling, the abutment G, above the drawhead, having the guides g, passage h, and stop 8 at the upper end of said passage, the bevel-headed Vertically-reciprocating trip K, the pin-slide H, the pin-lever L, having a raised arm, It, and the pivoted prop-catch a, substantially as specified.

3. In an automatic car-coupling, the combination, with a flat solid link-bar, D, having pin-slots near each end, and a draw-head having a narrow throat, a, of a pin-lever, L, a propcatch, a, jointed thereto, a pin pivoted thereto, a vcrtically-reciprccating trip, K, and a stop, 8, substantially as specified.

4. In a car-coupling, the removable abutment-guide G, having the arms b, seated in apertures 0, extending downward into the drawhead, and in connection therewith the transverse horizontal passages d, intersecting the apertures c, the transverse horizontal pins 6, seated therein and passing through perforations in the arms of the abutment, and the end fastenings, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence .of two witnesses.

GEORGE M. HARBAUGH.
